Developmental response of nymphs of Podisus maculiventris (Heteroptera: Pentatomidae) reared with low numbers of prey
Environmental Entomology 23 (2), 374-380
Abstract: Effects of maternal diet, maternal age, and nymphal diet on developmental time and survivorship of nymphs of Podisus maculiventris (Say) were studied using Mexican bean beetle, Epilachna varivestis Mulsant as prey. Developmental time of nymphs was shorter if nymphs were well fed and came from well fed and young mothers than if nymphs were poorly fed and came from poorly fed and older mothers. Nymphal survival was related to nymphal diet. Well-fed nymphs showed higher survivorship than poorly fed nymphs. Nymphs supplied prey at the lowest rates failed to reach adulthood and died, usually in the act of molting. Body sizes of adults from well-fed nymphs were larger than those from poorly fed nymphs. Impact of maternal effects on population dynamics of P. maculiventris is discussed.
